DANIEL W. ALDERMAN, OF COVINGTON, VIRGINIA, ASSIGNOR OF ONE-THIRD TO JOHN W. GOODWIN, OF SAME PLACE.

CAR-COUPLING.

SPECIFIGATION forming part of Letters Patent No. 673,938, dated May 14, 1901. Application tiled December 20, 1900. Serial No. 40,569. (No model.)

To all whom it may con/cern:

Be it known that I, DANIEL W. ALDERMAN, a citizen of the United States, residing at Covington, in the county of Alleghany and State '5 of Virginia, have invented certain new and useful Improvements in Car-Couplers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it apio pertains to make and use the same.

The invention relates to car-couplers.

The object of the invention is to provide a removable shoe for the knuckle of the carcoupling to take up the wear andwhich shall be of such construction that it Will fill the slot usually formed in knuckles for the insertion of links when one of these automatic couplers is connected to a car employing a link coupling, thus making a smooth joint at zo the slot to prevent chipping and damage, which have heretofore taken place at this point and which have materially reduced the life and usefulness of the coupler.

Vith this and other minor objects in View the invention lconsists in certain novel features of construction, combination, and arrangement of parts, which will be more fully described, and particularly pointed out in the appended claim.

3o' In the accompanying drawings, Figure lis a perspective view of a car-coupling knuckle. Fig. 2 is a horizontal sectional view through the same.

Referring now more particularly to the ac- 3 5 companying drawings, the numeral 1 denotes the car-coupling knuckle, which., is in the form of the Well-known .Ianney type of carcoupling, having a transverse link-slot 2 and pin-aperture 3.

4o 4 denotes a rail-shoe which is-fitted to the inner face of the knuckle, where the greatest wear comes, and is provided with a laterally-extending block 5, which conforms to and entirely fills the link-slot and is provided with ,a vertical aperture 6, which registers with the pin-aperture, so that the shoe may be retained in position by the ordinary pin 7, which has been heretofore used for connecting the knuckle with the car employing the old-style link-and-pin coupling. face of the knuckle is recessed, as shown at 8, so that the shoe when fitted to the knuckle may conform to its general contour and present no abrupt points. The recess 8 is made in angular form in the face portion of the knuckle and isv constructed so as to terminate in a shoulder formed at an angle to the rear wall of said recess, so as to create a seat for the shoe, the shoe conforming to the shape of the angular recess of the knuckle, 6o whereby when said knuckle is in use the shoe is held in place and no strains are transmitted to the pin 7, which simply serves to hold said shoe in position.

By the employment of a shoe the life of a knuckle is materially increased, not only from the fact that the shoe may be removed when worn and replaced with a new one, but, furthermore, for the reason that the link-slot formed in the knuckle is entirely filled by the 7o block of the shoe, thus preventing the chipping of the edges of the slot, and the pin being located in the aperture prevents bending and collapsing of the knuckle, thus making generally a much stronger knuckle and one of increased durability.

From the foregoing description, taken in connection with lthe accompanying drawings, the construction and mode of operation of my improved car-coupler will be readily under-V 8o stood without requiring a more extended explanation.

Various changes in the form, proportion, and minor details of construction may be made within the scope of the invention Without departing from the spirit or sacrificing any of the advantages thereof.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, S- 9o In a car-coupling, the combination with a knuckle provided with the usual link-slot, and pin-aperture, the face portion of the knuckle having formed therein an angular recess, its forward portion terminating in a shoulder arranged at an angle to the rear wall The 5o of said recess, of a shoe conforming to the shape of the recess and shoulder of the knuckle and having a block which projects into the link-slot, said block having an aperture similar to that of the knuckle and a pin inserted through both apertures, substantially as set forth.

In testimony whereof I have hereunto set my hand in presence of two subscribing Witmesses.
